Complex congenital lacrimal drainage anomalies are known to be associated with several syndromes and present unique surgical challenges. Duplication of human body structures is uncommon and has been reported in the uterus (uterine didelphys), ureter (duplex ureter), duodenum, transverse colon, and nose. Lacrimal drainage anomalies have been reported in proboscis lateralis. To the best of the authors' knowledge, there are no prior reports on duplication of the lacrimal sac. The present case reports a complex congenital nasolacrimal duct obstruction that was associated with duplication of the lacrimal sac and the presence of 3 canaliculi.
复杂的先天性泪道畸形与多种综合征有关，并呈现出独特的手术挑战。人体结构的重复并不常见，已在子宫（双子宫）、输尿管（重复输尿管）、十二指肠、横结肠和鼻子中报告过。泪道畸形也已在副鼻（proboscis lateralis）中报告过。据作者所知，尚无关于泪囊重复的报告。本病例报告了一例复杂的先天性鼻泪管阻塞，该阻塞与泪囊重复和存在 3 条泪小管有关。
